Thisinvention aims to provide a simple "means whereby a bag may "be held 'oiithe end of afeed or discharge spout, the con aws, and for limiting the movement of the jaws as they swing to an inoperative position. v I

It'is within the province of the disclosure to improve generally and to enhance the i i utility of devices of that type to which the invention appertains. p 1 With the above and other objects in view, which will appear as the descriptionproceeds,the invention resides in the combination and arrangement ofparts and in the details of construction hereinafter described and 'claimed,'it being understood that changes in theprecise embodiment of the invention herein disclosedymaybe made within the i scope of what is claimed, without departing from the spiritof the invention; t In the accompanyingdrawings-:

Figure lshows' in elevation, a device constructed in accordancewiththeinvention;

. In carrying out the invention the delivery spout is provided at its lower or discharge end with a ba receivin ortion that is, a

part adapted toextend into the-bag which is to befilled. This bag receiving portion may be of any suitable shape and size but preferably it extends outwardly from the body of the spout so as to provide a shoulder or for the purpose of illustration only.

ledge on which the bag may be supported. j

Cooperating with this bag receiving portion of the spout is a movable retaining device comprising'prongs so arrangecl that theywill pierce the'bag on difierentsides ofthespout and will enter seats or apertures'in the spout. 1

The retaining device may take various forms,

preferably it comprises two partsor jaws,

arranged on opposite sideswof the spout and provided with a plurality of prongs. These j aws are movably mounted on the spoutabove thedischargeiend thereof so that they may be moved into and out of position toengage the bag. It is also. preferable f that':n1eans shouldbeprovided forsiniultaneously op erating the two members of theretaining de- 7 vice and. this may, if. desired, be accomplished by means ot "a single actuating device. It will, of course, be obvious that the mechanism may takevarious forms and that that form here illustrated has been chose In the particular embodiment of the invention which is here illustrated the numeral 1 marks a feed spout, including a tubular body Qhaving a flared lower end 3 provided, with 1 openings or seats 4. A support 5, in the form of a plate, is1secured to one sideof the feed spout 1. A .supportfi, in the form of a plate,

isdisposed at the oppositefside of the 'feed spout 1, but is spaced horizontally from the feed spout'as Figure 2will. show. Spacers 7 are-positioned between themsupport: 6 and the feedspout .1. Securing elements 8, which may be bolts, are mounted in openings il in the support6. The securing elements 8 pass through the spacers 7 and are engaged with thefeed spout 1v to hold'the plate 6 thereon as clearly shown 'in Figure 2. In its lower edge, the support or plate 6 is provided with bearing notches 10f Alatch 11, in the form of aplate, is pivotally connected at one corner asshoWnatlQ to the bearing plate 6, and

has swinging movement in a plane parallel to a the plate 6. The latch. 11 is supplied in its. upper edge with hearing notches 14; The latchll isadapted to be swung upwardly behind the plateti so that the upper ends of the bearing notches 10 will cooperate with the notches l lof thelatch 11 to form bearings,

as will be described hereinafter. In order to hold the latch plate 11 in the position speciflcd, a securing means, such as a bolt and wing nut 15 may be mounted in registering openings 16 formed in the latch 11 and in the plate 6.

As here shown, the retaining device comprises a pair of horizontally extended U- shaped jaws 17 which are supplied with spaced prongs 18 adapted to cooperate with the seats a in the end 3 of the feed spout 1 to hold the bag, the bag being shown in dotted lines in Figure 1 of the drawings. The jaws 17 are provided at one end with upwardly extended arms 19 terminating in inwardly prolonged fingers o-r shafts 20 which are mounted to rock in the support or plate 5. The jaws 17 are equipped at their opposite ends with upwardly extended converging arms 21 terminating in outwardly extended shafts 22' that are journalled for rotation in the bearings formed by the notches 10 and'le of Figure 4. It may be noted profltablyatthis place, that by removing the bolt and wing nut, the latch 11 can be swung downwardly into the position shown in Figure 1- of the drawings and, thus, the jaws 17 may be removed, or

mounted in place, without disturbing either the supporting plate 5 or the supporting plate 6. One of the shafts 22 has an upwardly extended handle 23 carrying a weight 24:. In-

termcshing gears 25 are secured to the shafts 22, and are provided at their upper ends with cooperating shoulders 26:

hen the parts are arranged as shown in Figure 1 of the drawings, the prongs 18 on the jaws 17 extend through the upper end of the bag, and enter the seats 1 in the flared end 3 of the spout 1, the bag thus being held securely in place. The handle 23 extends far enough to the left (Figure 1) of a vertical plane passing through the shaft that carried the handle 23, so that the weight 24 will have a tendency to hold both of the jaws 17 down on the bag. The operator can swing the handle 23 to the right in Figure l, to move the jaws upwardly, to an inoperative position, thereby to release the bag, and when the shoulders 26 on the gears 25 come into abutment, they will be held in abutment, and the jaws 17 will be held in an inoperative position, because he weight 24 will extend to the right, in Figure 1, with respect to a vertical plane passing through the particular shaft 22 which carries the handle 23.

It will be noted that the construction and arrangement of the retaining devices, each consisting of a transverse member 17, its prongs 18, and the arms 21, are such that the transverse members and prongs will approach the apertured supporting portion 3 of the spout in substantially the direction of the length of the prongs. Thus the prongs will be caused to extend perpendicularly to the surface of the flared portion of the spout as they approach the same and consequently will pierce the bag and enter the apertures *ithout contacting with or dragging over the surface of the spout, or displacing the bag with relation to the spout.

Having thus described the invention, what claimed is 1. In a bag holding device, a spout having a downwardly flared bag receiving portion provided with apertures, and a retaining device comprising a member extending transversely to said spout, shaped to conform substantially to the contour of the adjacent part of said flared portion of said spout and having prongs arranged to extend substantially perpendicular to the surface of said flared portion of said spout when said transverse member is located adjacent thereto, and arms extending upwardly from the respective ends of said transverse member and pivotally mounted on the respective sides of said spout, said arms being so arranged with relation to said spout and said transverse member that when they are moved downwardly said transverse member will be moved toward the flared portion of said spout in substantially the direction of the length of said prongs.

2. In a bag holding device, a spout having a downwardly flared bag receiving portion provided with apertures, a pair of retaining devices each comprising a member extending transversely to said spout, shaped to conform suosrantially to the contour of the adjacent part of said flared portion of said spout, and having prongs arranged to extend substantially perpendicular to the surface of the flared portion of said spout when said transverse member is located adjacent thereto, and arms extending upwardly from the re spective ends of said transverse member and pivotally mounted on the respective sides of said spout, said arms being so arranged with relation to said spout and said transverse member that when they are moved downwardly said transverse member will be moved toward the'flared portion of said spout in substantially the direction of the length of said prongs, means for causing said retaining devices to move in unison, and a Weighted actuating arm connected with one of said retaining devices and arranged to hold both retaining devices in their operative positions or in their inoperative positions.

in testimony that I claim the foregoing as my own, I have hereto affixed my signature.
